For Tiffani Thiessen, cooking is a family affair. The host of Dinner at Tiffani’s found a love for the kitchen through her mom and grandmother before her, and now she’s passing on that affection to her kids.

“I grew up in a long line of women who love to cook,” Thiessen tells PEOPLE, “I just kind of went right into it with them. As I’ve gotten older and I started traveling to other countries, my love of cooking just expanded.”

She and daughter Harper, 5, work together on their favorite breakfast most mornings.

“Being from California, avocado toast is very popular in our house, we have it almost every morning,” Thiessen says. “She loves making that—I think she just likes smashing up the avocados!”

Thiessen kicks off her day with the Instagram-friendly breakfast, all part of her goal to eat healthy post-baby.

“I wish I could eat what I want, but I just had a baby a couple months ago, so I’m trying to eat healthier these days,” she says. “I try to use a balance of the 80/20 percent, where 80 percent of the time I’m eating very well, and 20 percent of the time I’m a little more adventurous.”

To lose the baby weight she gained while carrying her 11-months-old son Holt, the 5’6″ Thiessen is focusing on boosting her protein intake and banning bad carbohydrates from her diet.

“For me, it’s high protein, and really coming down on the carbs, or the bad carbs, as much as possible,” she says. “I’m nursing, so I can’t be too crazy and really be minimal, so I try to eat a whole grain everyday because I think it’s important, and because I want to give my baby everything he needs too. He’s not on a diet!”

Thiessen’s meals are impressively well-rounded, says dietician Keri Glassman of nutritiouslife.com. “That is an excellent, portion-controlled dinner,” Glassman says. “It’s veggie-heavy, with adequate protein and a little fat.” Her post-gym protein shake is “great,” because she’s “getting protein, which is satisfying, and calcium.” But she could easily add in almond butter or ground flaxseeds to increase her low calorie count for the day. Overall though, her meals are “excellent.”
